4 0

Answer:

I believe the answer is A

He is correct. If the second equation is multiplied by 2 and added to the first equation, the result is 0=3 , which means the system has no solution.

Identify the domain of the function shown in the graph.
Zarrin [17]

Answer:

A. x is all real numbers

Step-by-step explanation:

A function f from a set A to a set B is a relation that assigns to each element x in the set A exactly one element y in the set B. The set A is the domain (also called the set of inputs) of the function and the set B contains the range (also called the set of outputs).


As you can see from the graph x is valid for all real numbers. This is true because this function is continuous. Another characteristic of this function is that it is periodic.

Find the common ratio of the geometric sequence.
Kay [80]

Answer:

The common ratio is \frac{1}{x^4}

Step-by-step explanation:

Geometric sequence:A geometric sequence is a sequence in which the ratio of any term to the preceding term of that term is always constant.

Common ratio: The ratio of any term to the  preceding term of that term.

The n^{th} term of a geometric sequence is represented by  a_n=ar^{n-1}.

The 1^{st} term of the sequence = a.

The sum of first n term is

S_n=\frac{a(1-r^n)}{1-r}

The common ratio = r.

Given geometric sequence,

\frac{1}{x^{10}} , \frac{1}{x^{14}}, \frac{1}{x^{18}},\frac{1}{x^{22}} ........

The common ratio is

=\frac{\textrm{second term}}{\textrm{first term}}

=\frac{\frac{1}{x^{14}}}{\frac{1}{x^{10}}}

=\frac{x^{10}}{x^{14}}

=\frac{1}{x^4}

How do i solve this slope of a line from a graph?​
Tema [17]

Answer:

How you solve it is you pick two points on a line and figure out their coordinates. Determine the difference in the y-coordinates of those two points. Then you also do the same thing with the x-coordinates. Then you divide the difference in the Y and X coordinates .

Step-by-step explanation:

hope this helps 100% sure though that it is right.
